I've had success with three different brands: Sunbeam, GE, and Black & Decker. One was $4 from Goodwill and lasted a couple years, another was new in the $20 range probably 8-9 years ago and still going strong, another more recent is larger and hubby likes it to iron his work clothes ($30-40).
Keep in mind the weight of the iron. If it's too light, it tips over easily. If too heavy, it puts strain on your shoulder and wrist. The other features I consider are 1) how easy to see the water inside the reservoir 2) auto shut-off --a must for me 3) high wattage 4) is it cute? LOL
